In the US, we've essentially banned swimming outside of a few lifeguard-monitored zones. There are no swimming signs everywhere and in places you wouldn't otherwise think should be banned, such as public lakes or beaches. People still do swim in these areas, but I remember a squad of cop cars showing up at Lake Artemesia near UMD because a woman was gasp swimming in the lake.

I guess that hasn't been my experience. I see people swimming all the time in locations where there aren't lifeguards and other safety measures.

In the US, I find swimming holes all over the place without lifeguards and without swimming restrictions. I guess it depends on the area.
